Benefits of a Rigid Cover Board in Commercial Roofing Systems

Sponsored by Georgia-Pacific Gypsum

Learning Objectives:

  1. Discuss the evolution of roofing cover boards from the 1970s to present day, particularly in light of the use of single-ply membranes.
  2. Explain how the forces of nature (i.e., fire, wind uplift, moisture, hail/puncture, foot traffic, and sound) affect roof function and durability of different types of roof cover boards.
  3. Summarize the advantages related to the construction process and cost benefits when including a cover board in all types of commercial roof assembly design.
  4. Identify the roof system types, specialty systems (i.e., photovoltaic and vegetative roofs), and attachment options that can be utilized specifically with glass mat gypsum cover boards.

Georgia-Pacific Gypsum The Georgia-Pacific DensElement® Barrier System, with AquaKOR Technology, integrates the gypsum core and the fiberglass mat to form a hydrophobic, monolithic surface that blocks bulk water, but allows vapor to pass through. The Georgia-Pacific DensElement® Barrier System eliminates the need for building wrap, fluid-applied membranes or peel-and-stick membranes. It’s faster to install and can be installed when it’s wet outside–saving time and labor. The all-in-one Georgia-Pacific DensElement® Barrier system is finished with DensDefy Liquid Flashing to fill and seal joints, fasteners, openings, penetrations and transitions. The Georgia-Pacific DensElement® Barrier System is ABAA listed and WRB-AB approved and has a customized MasterSpec® specification –061656 Air and Water Resistive Sheathing Board.
